Nobsound springs - load range


I want to try out the Nobsound springs as damping footers (mainly under my mono blocks and my streamer). I ordered a first set of them and now I wonder about the amount of springs to put in for different weights of equipment.I remember one post that said it works best when 50% compressed (was it @millercarbon?).

I measured the compression of the springs, it takes ~2.5 kg per spring to compress it to 50%. Based on 50% compression target, this yields the following sweet spot configurations (only stable ones, total equipment weight):
- 3 units, 3 springs each: 22.5 kg
- 4 units, 3 springs each (or 3 units, 4 springs each): 30 kg - 4 units, 4 springs each: 40 kg
- 3 units, 6 springs each: 45 kg
- 3 units, 7 springs each: 52.5 kg
- 4 units, 6 springs each: 60 kg
- 4 units, 7 springs each: 70 kgLoad can be considerably higher than expected (somewhere I read about 36kg, which is presumably for 4 units).

Any comments?What about ~10 kg streamer, seems to be too light to compress the springs enough? Does anyone have experience with Nobsound springs under light equipment like this?
Based on your experiences: Would you even dare to put an 80kg floor standing speaker on Nobsound springs?

Granite sounds terrible. 4 x Nobsound springs with 1 spring in each under my 13 pound phono amp work well.

I’ve Nobsound springs under 11 pieces of equipment. All with 3 footers under each.

A quick way to damp the Nobsound is to wrap 1 turn of PTFE plumber's tape around the outside of the space between the plates touching all the outer springs.

@ryder I ignored that sheet and load by ear. Mine have less compression and sound best when they bounce. 

Try them without the included rubber pads too. Try them under component base not under existing feet. I’ve only used them on tube amps (and turntables) so can’t speak for solid state.

@curiousjim Hi Jim. Put them under the component not under the feet. I tried it once and didn’t like it. But I use tubes. However, @ghdprentice found that it worked. Use the necessary number of springs for each of the 3 points under the component so that the component is level after the set up. Obviously, use 4 under speakers. I can’t state it clearly enough - try difference configurations by listening. e.g. try it at 20% and 50% compression, under feet or chassis, 3 vs 4 etc.

@ghdprentice  Thanks for confirming. 

Oops. My bad. I moved mine from under feet to under the chassis. Sounds better
